Sure, but then the TBODY is going to be created automatically so it
will be there in the DOM.

Really? I'm asking because I didn't actually test that and it
surprisese me. If the TABLE contains a TR then a TBODY must be created
implicitly. According to DOM spec.
For example in DOM 2 html
"insertRow modified in DOM Level 2
Insert a new empty row in the table. The new row is inserted
immediately before and in the same section as the current indexth row
in the table. If index is -1 or equal to the number of rows, the new
row is appended. In addition, when the table is empty the row is
inserted into a TBODY which is created and inserted into the table. "

That[s correct behavior.

Sure.
